在 Fedora-38 上，路由表 (ip r) 不断变空。我可以通过重新启动 NetworkManager (systemctl restart NetworkManager) 来解决这个问题，只需几分钟。需要永久修复它。有什么建议吗？
观察到的其他怪异现象... 有时，我可以找到 (nmcli dev wifi) 同一 2.4GHz WiFi 网络的两个 BSSID。这是什么原因造成的？
$ nmcli con show

3c58ac2.4 e45b3590-2220-4dbd-8d0e-1ee7b0fdfd30 wifi wlp5s0

您看不到的是所有三个接口（wlp5s0、enp8s0、enp9s0）都显示为棕色（大概是因为它们都在“获取 IP 配置”。有时当它们都为棕色时，就可以访问互联网，决定因素似乎是内核具有非空路由表（ip r）。
NetworkManager 不断发送通知，称由于 IP 配置不可用，接口已被停用。
网络接口已在系统设置连接中（完全？）配置，并为每个接口指定了路由器和一对 Google DNS 服务器。
更新：1) LAN 接口现在确实处于绿色状态（并且不再显示“获取 IP 配置”，但 WiFi 接口却没有随之变化。2) 路由表仍然会自动重置（原因不明）。有时重新启动 NetworkManager 不足以恢复路由表，我必须重新启动接口（我在重置 NetworkManager 之前这样做）。
我错过了什么？
以下是一些日志文件摘录...
